From Seed to Sustainability: How Cannabis Companies Are Going Green
The cannabis industry, historically focused on reducing costs, is now at a critical juncture where sustainability is evolving from a secondary concern to a central operational strategy. More operators are recognizing that environmentally responsible practices can be both economically beneficial and essential for long-term viability as consumers look for organic products that are grown and processed responsibly. Companies like Ziel, a leader in the use of radio frequency technology for the decontamination of cannabis flower, demonstrate that sustainable practices and cost-efficiency can align, making a powerful case for greener practices.
The Investment in Sustainability
Implementing sustainable practices often demands upfront investment and resources, but the long-term benefits are significant. Similar to cannabis cultivation, agricultural farmers are going green by incorporating sustainable tech into their operations. For instance, while robotics and AI are no strangers to agriculture, Carbon Robotics is utilizing a LaserWeeder system to help eliminate weeds from various crops—all without relying on toxic chemical herbicides or disruptive soil practices. Carbon Robotics helps farmers reduce the high cost of manual labor while also providing USDA organic farmers with a solution for removing weeds without the use of herbicides. These efforts not only foster a loyal customer base dedicated to environmental responsibility but also establish the farmer and tech providers as leaders in the organic sector.
The Path to Certification
Currently, cannabis products lack the ability to be USDA Organic certified due to the plant’s federal status as a controlled substance. However, with the potential for cannabis to be reclassified as a Schedule III substance, there will be an opening for FDA oversight, which could pave the way for USDA and National Organic Program (NOP) standards to apply to cannabis cultivators in a similar manner as the agricultural food industry. If this occurs, cannabis products adhering to these standards may finally earn organic certification, aligning with the guidelines currently applied to food and supplements. Not only do cultivation protocols determine organic certification, post-harvest processes impact certification as well. Therefore, selecting a microbial control solution technology that is compliant with organic processes is critical.
Sustainable Microbial Control Methods
Radio frequency is a non-ionizing radiation treatment that has been used to pasteurize food products for decades. It is considered safe for consumer consumption by the FDA and USDA, as well as compliant with NOP organic processes. Products treated with ionizing radiation are ineligible for organic certification under USDA and FDA guidelines. In Canada, the Radura symbol is required for both food and cannabis products exposed to ionizing radiation like gamma, e-beam and X-ray options. These treatment methods are effective but controversial, as ionizing radiation can alter the molecular structure of cannabis, potentially impacting its terpene profile and other active compounds.
A non-ionizing treatment like radio frequency technology offers several advantages for sustainable cannabis processing. Unlike traditional decontamination methods that are energy and resource intensive, the Ziel RFX requires only electricity and processing bags—eliminating the need for chemicals or waste disposal. For instance, the RFX can decontaminate 160 lbs of cannabis in just 8 hours for under $10 in electricity, reducing environmental impact while boosting energy efficiency.
Conversely, ionizing cannabis remediation technologies have other associated costs outside of regulations. For example, e-beam and gamma remediation must be done off-site, costing cultivators time and money for transportation, insurance, and administration. X-ray equipment can be installed on-site, though it does require the installation of additional chiller equipment, adding cost and an additional layer of initial permitting and annual renewals. Radio Frequency remediation, on the other hand, doesn’t call for any extra licensing, labeling, or facility upgrades. It can be done on-site, and the technology has already been screened by the USDA in other applications.
Lastly, the Ziel RFX device is designed with a lifespan of over 20 years, eliminating the need for frequent parts replacements and significantly reducing waste. Unlike other market options, which often require ongoing repairs or major modifications to facilities, the RFX is a durable, cost-effective solution that supports both sustainability and operational efficiency in the long term.
Technologies like radio frequency, provide a sustainable solution for microbial control that aligns with both U.S. and Canadian organic guidelines and with Good Manufacturing Practices (GMP) certified operations in the U.S. and E.U.
Pathways to Sustainable Certification
As the industry awaits the possibility of federal organic certification, cultivators can seek alternative credentials. Programs like Envirocann and EnvirOganic, are geared toward those with strict adherence to sustainable farming practices and manufacturers who follow strict compliance in a laboratory setting, GMP, and environmental awareness. Coastal Sun Farms, in California, exemplifies this approach with its commitment to ecological farming.
Another prominent option is the Clean Green Certified program, the largest and most awarded cannabis certification, promoting sustainable practices. CULTA, a Maryland-owned craft cannabis brand, was the first farm in the state certified by Clean Green for its no-till farming methods and integrated pest management, which includes the use of beneficial insects in the live soil.
Beyond Cultivation: Sustainable Sourcing
Sustainability is not limited to cultivation. Many companies incorporate ethical sourcing practices into their supply chains. Grön, a cannabis edibles brand, achieved a milestone in 2019 as the first cannabis chocolate brand to receive Fair Trade certification, supporting sustainable income for cocoa farmers and their communities.
The Future of Sustainable Cannabis
As environmentally responsible practices continue to gain momentum in cannabis, the industry is moving toward more sustainable hardware and ethical processes. Cultivators and manufacturers adopting eco-friendly methods—whether through certification programs, Fair Trade sourcing, or energy-efficient technology—are setting the stage for cannabis to become a model of ethical and sustainable operations. This dedication will not only enhance consumer trust but also contribute to a greener, more sustainable future for the industry and the planet.
